Each hot plate is made with a cast aluminim chassis that is painted with chemically resistant epoxy paint. The chassis is designed to keep spills out of the case.
Heating and stirring controls are solid state with individual indicator lights which illuminate when either is activated. The controls are well forward of the heater surface to prevent accidental burns. Additionally, the solid ceramic heater plate is framed in cast aluminum and is designed to keep heat from the edge of the heater plate. .
The stirrer features a solid state control capable of stirring an aqueous solution from 100 to 1500 rpm. The control has an OFF position fully counter-clockwise, and is continuous over 270 degrees of rotation from minimum to maximum speed when turned on.
The magnet is a circular disc with twenty pound pull strength and is capable of stirring more than two liters of aqueous solution.
The heater control has OFF, LO, and HIGH positions for quick setting, and a smooth infinite control of about 270 degrees between LO and HIGH settings. The control will regulate a set point to ± 2.5° C.
Control knobs are specially selected to provide easy use and positive, tactile feel. All units are fused, and have a 3-foot long detachable AC line cord with a male plug that matches the local standard. The warranty is 12 months.
